WHAT IS A FUEL CELL?WHAT IS A FUEL CELL?• Generates electricity by chemical reaction
• Two electrodes anode and cathode
• Every fuel cells also has an electrolyte
• Hydrogen is the basic fuel, it also require oxygen
• Making power more efficiently and with less pollution
• Water is the only by product

PRODUCTIONPRODUCTION
Hydrogen can be produced from
• Fossil Fuels (currently 90% of 42 tons/year)
• Water

OTHER TYPES OF FUEL OTHER TYPES OF FUEL CELLSCELLS•Alkaline fuel cell (AFC)
•Phosphoric-acid fuel cell (PAFC)
•Solid oxide fuel cell (SOFC)
•Molten carbonate fuel cell (MCFC)

ATTRACTIONSATTRACTIONS• High energy conversion efficiency
• Modular design
• Very low chemical and acoustical pollution
• Fuel flexibility
• Cogeneration capability
• Rapid load response
6/02/2014 DEPT.EEE.SIST 19
HH22-O-O22 FC EFFICIENCY FC EFFICIENCY• 40% efficiency converting methanol to hydrogen in reformer
• 80% of hydrogen energy content converted to electrical energy
• 80% efficiency for inverter/motor
• Converts electrical to mechanical energy
• Overall efficiency of 24-32%
6/02/2014 DEPT.EEE.SIST 20
PROS & CONSPROS & CONS Advantages• Water is the only discharge (pure H2)• No conventional energy sources needed.• Low heat transmission. • Cost effective method to produce electricity.
Disadvantages• CO2 discharged with methanol reform.• Little more efficient than alternatives• Technology currently expensive.
